Fix inaccurate description of Challenge 4

[Tunzeki]

In Challenge 4 (Remove unnecessary state), the last sentence of the first paragraph says that the alert always shows "Hello, !". It doesn't. What actually happens is that "Hello, !" is alerted the first time you enter a name, but subsequently, the name you entered just before that time is shown.

Example:

1. Say you enter John the first time. Alert: "Hello, !"

2. Next, you entered Jane. Alert: "Hello, John!"

3. Finally, you entered Jack. Alert: "Hello, Jane!"
